Synthesis and characterization of zincosilicate and pure-silica SSZ-42 and SSZ-71

In this paper we report, for the first time, the synthesis and characterization of new zincosilicate Zn-SSZ-42. New method of synthesizing pure-silica SSZ-42 via the OH– route without using F– anions is presented. Furthermore, the synthesis and characterization of the novel layered zincosilicate and pure-silica designated as SSZ-71 are discussed.
